To all 'whom 'it may concern."

. Be it known that I, SOCRATES A. XirPAs, a citizen vof the United States, residing at Pittsburgh, in the county of Alleghen and State of Pennsylvania, have invente 'certain'fnew and useful Improvements in Electric Fans, of which cation. y p

My invention relates to electricians.` The object of the invention is to provide a device. which will' rduce a la e-aniount of air blast and to li the ,following is a specitake the place of the ordinary buzz oscillating fans and their crudeandA intricatel mechanism as in my invention therel are only two bearings and no interior working ,l

' parts liable to et 'out of order.

A furthero ject ofthe invention is to provide means whereby the "blast `may be regulated so as to blow in 'any 'one' or more directions, when it is. not ydesired to have the fan discharge in all possible directions, which directions are-included in a horizontal zone surrounding the central portion of the fan." I,

'Further objects and advantages will be more fully described herein and specifically pointed 'out in the claimsh'ereunto annexed, recourse -being had to the accompanying drawings forming apart 'tion in which Figure 1. is a viewbf the complete fang.

Figure 2 is a view of the upper portion of thefan showing-the blast re lating or cut olf 'plates on `the perforat casing or VSphere-i y Figure 3 is a erspective view 'of one of the blast shut o or cut out plates.

Figure-4 is an edge view o the 'obl-iquely or angularl disposed rotary disc showing two depending blades or wings in side elevaz tion.. i

Figure 5 is a plan of the obliquel mounted rin showing 'an edge view of t e wings or bl es; y

Figure A6 is the same as Figure 4 but showing' two wings or blades in side elevation above the ring or oblique disc;

ave 'no visib e movingparts which renders the fan absolutely safe of this specifica-` for Figure 7 is a perspective view of the oblique annulus or ring withits wingsor fragmentary cross sectionA an cage showing the bearing 4`for 'the' hub or center of the rotary wing mechanism f f or rotor and the bevel or angular ends of the saine. 1

Iii the drawings like reference numerals indicate similar parts in all the several views Referring to, Figure 1, 1 is the base or stand of the apparatus arranged in the ordi. naryinanner. 1

2. is a vertical motor adapted to have a vertical shaft, also, and to drive the hereinafter described rotor with its wings or impellets. A

,3 are the brush terminals of the motor leading to an electric suppl -and are .adapted to be attached to wires Y 6 is a switch, Figure 1', for regulating the speed of the motor in the usual manner.

Mounted on the upper end of the motor 2 is a spherical openwork ca e or shell entirely enclosingI the hereina ter described wing or impel mechanism which constitutes the blast making fan or rotor, and is vin two parts, the upper 7 and the lowerjportion 8 suitably united as at 7, in Figure 1.

The shaft 5 passes through the sphere lor globe 7 8, its lower end bein suitably mounted for rotation in thestep is 'in width as they approach the medial plane.

' -As shownlinfFigurelz, two kinds of cut out. portions: aire 'placed ontlie 'sphere or globe butj the ent-ire surface-of the ball-like cage maybe .nrovidedi with cutout portions of only one style1-that is, either the arcuate spaces 12 or the .qirtlior' horizontal slots 13* Upon the4 vshaftj at or near the central portion ofthe cageg-.glob'e or sphere ,778',L is placed a sleeve ,or oollarlll having an angular or'lbevellled portion 16;

I may dispense with the angular position\ ing of the fan or blast, element and place* it at right angles to the axis of rotation.

In order to provide means whereby the blast may be directed or restricted to a certain direction provide 'shutters or cut oft' plates 22 and A23 'conforming in shape to one eighth, more vo r less, of the surface of the sphere or globe. enclosure. T-S', Figures 2 and 8. The plates are provided with rings 2/1 atA their upper or lower portions7 the. eyev onhole of which is adapted `to be inserted over the boss 25 and the portion26, Figure 1.

In this manner the plates 22 and 23 can be rotated Ventirely around all portions of the sphere7-8, so that certain nulnber of. the out out portions 12 and'13 can beclosed or cut ofi and theblast of air directed at a-A givenpoint' or points at will.

rllhe plates for convenience, are provided ywithknobs 27 for facilitating the movement thereof. A

In the fan described, the motor by which the before-mentioned Wingso'r blades arelriven, is vertical so that it Vis not necessary or the lnotor to assume. -any angular positionas is done n the ordinary dise oi buzz fan and' which 'effective only. in jslnall areas'.- The useswof niy invention are 'niore rariedthan the 'ordinarypropeller fan and is'hettelr suited @for eoinuiereial uses besides being absolutely safewhere there are lchild-renas there'j-is no dangeifot" severed or injured linger I Fordrying"ladies hair :rlter s lian-ipo'oing,l the tan can be heldelosel oor` against the' .head Without -inconrenience o r danger and have the blast lto lilou' in all directrfinsf yAt'-diningftables, luneh counters and other places; the. blast is ifliretted to' :eaeli person alike and eliminates -i'igaf'klor rif large area i :rnd discharging ride :inf evenly heit 11.
